VENTILATOR.

Application filed latch 21, 1928. Serial 11 0, 545,489.

To all whom it may concern:

Be it known that ANDREW L. BIKER, a

' citizen of the United States,'and resident of Fai'rfleld, in thecounty of Fairfield and State of Connecticut, has invented certain newand useful Improvements in Ventilators, of which the following is aspecification.

This invention relates to a ventilator, useful for many purposes, butmore especially, adapted for use as a closure for transoms,

doorways, windows, panels, or the like.

An important object of the invention is to provide a ventilator whichwill be a novel, improved and compact article of manufacture, capable ofinsertion for use '1 with a minimum of effort by unskilled workmen,without danger of destroying the advantageous features for which theventilator has been devised.

A further and important object is to produce an efiicient and reliablearticle of manufacture of the present character which will be simplicityitself in construction and which can be quite inexpensivelymanufactured, most all of the parts of the present ventilator desirablyconsisting of sheet metal.

A still further and important objedt is.

to provide a ventilator consisting of a frame having a plurality oflouvers pivoted therein to turn on their axes and preferably soproportioned and arranged that when swung in one direction they willcompletely close the space within the frame and when swung in the otherdirection will leave passage ways between the respective louvers withoutopening a direct line of vision through the frame, and to equip theventilator with dependable operating mechanism of improved design forswinging ,the

louvers to open and closed position, the

operating mechanism including simple and un que devices limiting thedegree to which the louvers can be turned on' their pivots.

lVith the above objects in view, as well as others which will appear asthe specification proceeds, the invention comprises the construction,arrangement and combination of parts as now to be fully described and ashereinafterv to be specifically claimed, it

I being understood that the disclosure herein is merely illustrative andmeant to, in noway hmlt the spirit of the invention, chan es in detailsof construction and arrangement of parts being permissible so long aswithin the scope ofthe appended claims. v

In the accompanying drawing forming a part of this specification,

'Fig. 1 is a perspective view of the novel ventilator, showing thelouvers thereof in closed "position Fi .2 is an enlarged longitudinalsectiona view of the ventilator showing the louvers in open position;

Fig.- 3 isa view corresponding with the showing of Fig. 2, butdisclosing the louvers in closed position, and frame memberscorresponding with those of Fig. 9;

Fig. 4 is an enlarged fragmentary perspective' view of the right handend of the tailing the mechanism for operating the F ig.- 4, looking inthe direction of the arrows; and r Fig. 9 shows a variant form of framemembers.

The ventilator of this invention is constituted by .a frame ofrectangular configuration, louvers pivotally mounted therein, andmechanism for swinging the louvers on their pivots to open and close thespace within the frame.

The-,frame, as shown, sheet metal, it consisting of a top memberiij lO,bottom member 11, and side menrhers; denoted by l2 and 13, respectively.

As will be most clear from Figs. 1, 4 and '8, all of the members-of theframe are flanged plates, the top and bottom members having flanges,denoted b7 14 and 15, respectively, extending at right-angles for thefull lengthsof said members from their opposite edges, and the sidemembers having flanges 16 "extending atfgfifiht-angles from theiropposite edges and terminating short of the ends of the side members.The ends of the side members are provided s composed of bers to producethe frame will be best seen in Fig. 8. The opposite ends of the top andbottom members are arranged flush v 4 with the outer faces of the sidemembers, a de' endable bearing for the sp1ndle29, and

the end portionsof the flanges 14 and 15 are arranged contiguous withtheends of the flanges 16 in ahgnment therewith, and

the flanges 17 are situated contiguous with the inner faces of the endportions of the top and bottom members, and between theend portions ofthe flanges 14 and 15, re-' spectively. The connections between themembers may be made in some other manner, as by means of rivets, butas.- -shown said connections are made by providing holes 18 in theflanges 17 and drawing the metal 0 the end portions of'the top andbottom members into the holes 18 and then spreading the drawn metal, -asindicated at 19 in Fig. 8. I have used the terms top, bottom andside'members for the sak'eof convenience. vIt will be understood thatthe arrangement as described could be reversed if this isfounddesirable.

preferably being integral with and arranged at right-angles to the bodyportions: of the louvers. The louvers are pivotally mounted in the topand bottom members of the "frame in the manner best shown in Figs. 2 to6, 1I1Cll1S1Ve. at is to say, each of the ears 22 1s provide with holesrotatably receiving a drawn portion 24 of the metal of the top saidoperating bar being arranged beneath the midwidths of said member of theframe, and each of the ears 23 is drawn as at 25 to rotatably enter an.annular flange 26 consisting of upwardly drawn metal of the bottom plate6f the frame, the pivotal points for the louvers being arranged adjacentthe opposite ends ofv the body portions thereof preferably close toends. Numeral 27 denotes an operating ,bar for manipulating the louversupon their pivots,

the ears 23 to slide upon the bottom plate of the frame, and each ofsaid ears having metal drawn therefrom and 'rotatably entering holes 28at uniform distances apart inthe operating bar. The mechanism for movingthe operating bar longitudinally to turn the louverson .their pivots ina-manr ner which will be obvious, consists of a spindle 29 mounted inthe flanges 1p adj acent one side of the ventilator and having a crank30 and .a manipulating handle 31. Adjacent one of its ends the'operatingbar is bent to general U-shapeas denoted at 32 to receive the crank, and.the position 'of that end of the bar, denoted 33, beyond the'spindle isinsured bya'rod 34 situated directly" above the operating bar and havingits opposite ends located in the flanges 15. a

The metal of the flanges 15 is drawn as de noted at 35- and36,,respectively, to provide the -shaped part of the operating bar ispreferably arranged about the crank so that the slight forward andrearward movements of the operating bar when movedlongitudinally toadjustthe louvers impart slight endwise movement to the spindle.Obviously, the operating bar will insure the spindle againstdisplacement. The spindle has a reduced end 37 mounted in the bearing 35whereby, the larger diameter of the spindle can limit rearward'movementof the same. Forward movement of the spindle is checked by' engagementof the operatingbar with the front flange "15 of thebottom member.Obviously, the position of the spindle in its bearings is thus insured.Numerals 38 and 39 denote the body portions of end louvers fixed in theframe as by means of ears 40 desirably secured to the top and bottom'members by portions of metal drawn from the members and entering holesin the ears in about the manner-in which the ears-22 are secured to the-'top member. The body portion 38 is preferably arranged contiguous withthe rear flange 16 at-the right endof the ventilator aiid the body;portion 39 is preferably arranged contiguous with the ront flange 16 atthe left end .thereof. Numerals 41 and 42 denote extensions upon thelouvers 38 and 39 respectively, which may extend obli uel from the fixedlouvers inwardly oft e rame.

.In Fi 7 Ilhave shown the bearing 35 as arrange within an opening of thefixed louver 3 8, .and I have-shown the rod 34erten,din through said"louver, as Well as throug the flanges 15. The arrangement asillustrated is simply for the sake of convenience. I h

The throw of the crank 30 determines the distance the operating bar canmove longitudinally, and hence limits the degree to which the louverscan be turned on their pivots, as will be obvious, and the operating bar.,is of such length that when the louvers have been moved to wide openposition, the end of the bar, denoted by 43, spaced from the crank willengage the extension of the 'louver 39. to furnish a positive stoptending to make stable the open positions of the louvers. See Fig. 2.The c osed position of the louvers is made stable by the engagement ofthe ex- 1 ber of the frame'upwardl to form the annul'ar flanges 26', I.rovi e a space 46 be- I tween-the ears 23 an .B'y drawin fin s es andbottom members of the frame. I desirably utilize rivets 44 as shown inFig. 5

to first secure'the ears 22 to the top member of the frame. I thenassociate the'ears 23 the relative ositionsof the ears'23 and theottomfmem fr. the metal of the; bottom memthe bottom member toaifordfclearance for the longitudinal sliding movements of the 0 ratingbar upon the bottom member. T is will be most clear fromFig.6. i

The simplicity of the construction of the present ventilator is tobenoted. The frame consists of but four sheet metal plates rigidlysecured to each other. f The louvers each consist of' a single piece ofsheet metalsuitably bent and mounted in the frame. And the operatinmechanism for manipulating the louvers s constituted by an operating barand a crank with manipulating handle. The ventilator consistsofbut fewparts and the'relative positions of all of the parts are insured, therebeing no liability whatever that any part can become dislocated orimpaired. To incorporate the ventilator in its position of use all thatis necessary is to fit the frame into a transom, doorway, window,

' panel, or the like, the flanges l4 and 15 serving the purposeofinclosing the ends of the louvers and the flanges 16 interlapping withthe fixed louvers in such manner that the advantageous features of theventilator are preserved.

' In Fig. 9 I have shown a variant form of frame members. In saidfigure, numeral 47 represents a top or bottom member, and 48 representsa side member. A portion of the side member and its flanges 49, areoffset or drawn inwardly as denoted at 50 and the flanges 51 of the topor bottom member fit thereover toalig'n with the flanges 49. The

iconnection between the members 47 and 48,

shown, is made b passing through all 0 said flanges, a bushing means ofarivet 52 53, extending between the drawn in portions of the flanges 49and through which the rivet extends, serving to allow the rivet to clampthe drawn in portions 50 and flanges 51 against each other. By theprovision of elongated slots 54 in the drawn in'portions, the sidemember can be slightly adjustable in the top or bottom member. In thepresent form of the invention the bushing 53 can be located to serve thepurpose as described of the rod 34.
